For me its honestly a ton of my work software (digital forensics), shit is too niche to be replaced by good FOSS options. Cellebrite, Magnet Axiom, etc. Autopsy is great and free and has a linux version but it simply cannot get the same level of data without a pretty nutty level of custom code.
And the biggest side effect of this is FUCKING WINDOWS. God I would replace this nightmare OS in a heartbeat if the aforementioned work software would make linux compatible versions. We have legitimately wasted 10k hours dealing with windows bullshit that would not be a problem in linux. Though im sure linux would take a different 10k for its own problems.
What about you guys? Doesn’t have to be work related, thats just the thorn in my side right now.
Microsoft Office. If you need to do any kind of professional documentation for external organizations, it’s basically impossible to use anything else.
The lack of good support for MS Office formats in FOSS tools is Microsoft’s fault. Office itself often creates files that are slightly incompatible with their own published OOXML standard. FOSS tools are left chasing these inconsistencies. I wish the world had settled on ODF instead of OOXML for documents.
